Whether an iRex DR800 dock would allow charging is not as important as holding the reader in an upright position. This could be such a highly useful accessory that users of multiple displays and computers would welcome it for training, news monitoring, and reference.

m-edge makes a stand for many e-readers (ex: http://www.medgestore.com/products/k...-flexstand.psp), and for a while looked like they were planning to make one sized for the DR800. When they started shipping accessories for the 800 the stand went away though... They seem to be fairly responsive to customer demand, so it'd be worth e-mailing them that you'd buy one if they made it in the DR800 size.

Not working
The SanDisk SD Card 2 GB does not work reliably: many times the cards filsystem is not mounted at systemboot. When mounted, the card cannot be formatted by the systems' format tool. When mounted, it causes freezes while navigating the filystem after some time.
